How to fail a python unittest if the setUpClass throws exception

Question

I am having little trouble using the python setUpClass.

For example consider the following case

class MyTest(unittest.case.TestCase):

    @classmethod
          


        

Answer 1

import contextlib

class MyTestCase(unitest.TestCase):

    @classmethod
    def setUpClass(cls):
        with contextlib.ExitStack() as stack:
            # ensure teardown is called if error occurs
            stack.callback(cls.tearDownClass)

            # Do the things here!

            # remove callback at the end if no error found
            stack.pop_all()
